ROTOR HP DUPLEX self cleaning screen filters are designed for filtration of sea water or brackish water. Housing, covers and the most important components are made of DUPLEX steel to gives them exceptional resistance to wear and corrosion also in harsh environments. They can be supplied in two different configurations (L and O) depending on the position of In/Out connections. Special suction pads ensure the complete cleaning of the screen with minimum water consumption and without stopping the filtration process. The filtering cartridge can be supplied either as a polyester mesh inserted between two DUPLEX steel net tubes or as a DUPLEX steel cartridge (fito); with this solution the filtration degree ranges from 25 µm to 810 µm.
